First, any rver who has indulged in an electric jack will tell you, with or without remote controls, that they will never go back to the "ugh" and "oomf" of hand crank trailer jacks. It's like when someone breaks down and buys a dishwasher. Sure, washing them by hand is ok...but once they've experienced the luxury of the new gadget, there is no way they are letting you take it away!
Third, if you are making the investment...why not really treat yourself to the Husky Brute Jack with remote? Haven't we all been there....reading the level inside the trailer, running back to the jack, running back in the trailer...add some arctic wind or torrential downpour and you are set for misery. The remote works from 40 feet away! You can raise up and down without moving an inch. It isn't a necessity, but geez it would be nice, wouldn't it?
So there you have it - treat yourself to the Husky 87641 Brute Electric Jack with Wireless Remote - 4500 lbs. Capacity. It also is available without it, if you have a co-pilot who stays inside the rv and screams "higher" and "lower" during setting up camp. But think of the fun you could have with the remote. Just keep it away from a place where a gigantic rv cat like ours might lie on top of it...that would be quite a scare!
